CARPENTER S-GA GE.

SPECIFICATION forming part of Letters Patent No. 732,379, dated June 30, 1903. Application filed October 18, 1901. Serial No. 79,113. (No model.)

To all whom, it may concern:

Be it known that I, LEWIS SHIREMAN, a citizen of the United States, residing at Martinsville, in the county of Morgan and'State of Indiana, have invented certain new and 'useful Improvements in Carpenters Gages, of

which the following is a'specification.

This invention relates to improvements in carpenters try-squares andgages.

With the squares and gages in common use when it has been desired to mark oif a plank-as, for example, to make a pencilmark longitudinally of it to guide the saw in ripping a strip therefrom--it has been necessary to hold the rule or square in one hand and the pencil in the other and guide the marking by bearing with the finger against the edge of the plank. This while not being accurate subjected the finger to danger of laceration from splinters and other injury by rubbing contact withthe rough plank.

The object of this invention is to provide simple and eifective means for. holding the marking-point of a pencil at any desired and predetermined position of the tool during the marking operation and without exposing the operators hands or fingers to injury.

I accomplish the objects'of the invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my invention in operative position; Fig. 2, a plan view ofa try-square with my improvements supplied thereto, and Fig. 3 a like view of a similar tool differing only in having a forty-fivedegree bevel of the handle where it joins the blade.

Like letters of reference indicate like parts throughoutthe several views of the drawings.

A represents the blade of the square,and B the handle, both of which are of usual and well-known construction except as to such difierences as will be hereinafter specially pointed out.

The blade A will preferably be graduated intoinches or other units of measurement and fractional parts thereof, and for convenience the inches will be numbered from the marked off.

The marking is done by placing the handle of the square against the edge of the plank and drawing it from one end of the plank to the other with the pencil contacting through the proper hole in the blade with the plank.

The openings will generally be in more than one row in order to preventweakening the blade, as would occur by placing them all in a single row.

- The blade will preferably he graduated on both sides in the usual manner.

It is not desired to limit the invention to the rectangular -shaped openings, as obviously other shapes could be used in a practical way.

I am aware of the patent to Farnam, No. 17l,927,issued January 11, 1876, and do not claim the construction there shown.

Having thus fully described myinvention, whatI claim as new, and wish to secure by Letters Patent of the United States, is

In a tool of the kind specified, a blade having a graduated scale and rectangular perforationsv in a plurality of rows, therperforations of one row being staggered with relation to those of the next and each perforation having a side alined with one of said graduations.

In witness whereof I have hereunto set my hand'and seal, at Indianapolis, Indiana, this 28th day of September, A. D- 1901.

LEWIS SHIREMAN.
